I have already emailed Kelly Duffie about this. Sunday applied alum sulphate to 1 acre pound in same quantity as last year. Was dissolved this time. It does make a big difference if dissolved. According to the bucket tests, this amount should have been less than recommended and not had any affect on the fish. I have killed most of the small fish and a few larger ones. Been walking around in shock for almost 2 days now.

How long can I expect the effects to last on the fish that survive? How long should I wait to re-stock bluegill. I needed to remove bass but not this way. I did find out how many different sizes of the different fish I had and they were varied. Have had only a couple of dead catfish but saw a few in the shallows this AM which is not a good sign.

Advise, if you are going to use this chemical do so in small applications in moderation to determine the effects on the fish population. OR not at all.
